ONGOING PORTFOLIO MANAGEMENT
Currency and cross-border considerations
This is the last piece of Ongoing Portfolio Management. It isn't a task on a checklist — it's a layer of exposure that sits underneath everything else you hold.
Why currency enters the picture at all
Say you hold a U.S.-listed fund, but you live in Canada and spend Canadian dollars. Two things now move your return: how the fund performs, and how the exchange rate moves between the two currencies. The same thing happens in reverse for a U.S. investor holding a Canadian or an internationally listed fund. This exposure isn't something you actively chose — it comes from where the fund happens to be priced, not from anything the underlying companies themselves do.
​
Here's a simple example. Say a U.S. stock fund stays flat in U.S.-dollar terms over a year. If the U.S. dollar strengthens against the Canadian dollar during that same period, a Canadian investor still ends up with a gain, purely from the currency move. If the U.S. dollar weakens instead, that same investor could end up with a loss, even though the fund itself never actually moved.
Two places currency shows up
Currency affects a portfolio in two distinct ways, and it helps to keep them separate.
​
The first is conversion, which happens at the exact moment money changes from one currency into another — funding an account, buying a foreign-listed holding, or converting proceeds back later.
​
The second is ongoing fluctuation: the everyday change in what a foreign holding is worth once it's translated back into your home currency, independent of how the underlying investment actually performed.
Hedged vs. unhedged funds
Funds that hold foreign assets are typically built one of two ways. A hedged fund uses currency contracts to offset exchange-rate movement, so its return tracks the underlying investment's local-currency performance more closely. An unhedged fund instead lets exchange-rate movement pass straight through to the investor.
​
Which one makes more sense often depends on how you plan to use the money. Someone who spends only in their home currency, and wants their return to track the local market closely, often leans toward a hedged fund. Someone who's comfortable with extra ups and downs, or who expects to eventually spend the money in the foreign currency, might prefer to stay unhedged instead.
​
Hedging isn't free — it typically carries a small ongoing cost, often reflected as a modestly higher MER on the hedged version of a fund. Neither approach is inherently right or wrong. It comes down to a trade-off: pay a small ongoing cost to smooth out currency swings, or accept those swings in exchange for skipping the cost.
Why it's easy to miss
Conversion costs rarely appear as a separate, labeled fee. Instead, they're built directly into the exchange rate itself — the rate you're offered is a little less favorable than the true market rate, and that gap is where the cost actually lives. Two people converting the same amount through different channels can end up with noticeably different results, without either one ever seeing a distinct charge.
The all-in-one ETF and currency
Many investors hold a single all-in-one or asset-allocation fund instead of assembling a portfolio piece by piece. If that describes you, this particular currency decision has effectively already been made on your behalf.
​
These funds are built with a defined mix of stocks, bonds, and countries. As part of that design, they also carry a built-in mix of hedged and unhedged foreign exposure. You never see this decision directly — it's already embedded in the fund well before you buy it.
​
That doesn't mean the decision doesn't exist, only that someone else made it for you, based on how the fund was designed. If you're curious about the exact mix, it's usually disclosed in the fund's public fact sheet. Wanting more direct control over that mix is one of the few reasons a self-directed investor might move away from a single all-in-one fund toward separate, individually chosen holdings
When it becomes a bigger decision
For most people holding a globally diversified portfolio, currency exposure sits quietly in the background rather than requiring active, day-to-day management.
​
That changes for a smaller group of investors. Someone splitting time between two countries, holding dual citizenship, or maintaining accounts in a country they no longer live in ends up dealing with currency on a more direct, ongoing basis.
​
In those cases, currency intersects with tax and legal rules rather than pure investment mechanics, and those rules depend heavily on which two countries are involved. That's why they're addressed on their own dedicated pages rather than here.
